GEORGE PLANTE, OF LOWELL, MASSACHUSETTS.

COMBINED PIPE WRENCH AND CUTTER.

SPECIFICATION forming part of Letters Patent No. 506,0'70, dated October3, 1893.

Application filed March 24, 1893.

To all whom it may concern:

Be it known that I, GEORGE PLANTE, a subj ect of the Queen of GreatBritain, residing at Lowell, in the county of Middlesex and State ofMassachusetts, have invented a new and Improved Combined Pipe Wrench andCutter, of which the following is a full, clear, and exact description.I

The object of the invention is to provide a new and improved pipe wrenchand cutter, which is simple and durable in construction and arranged forconveniently turning a pipe or rapidly cutting the same in two parts.

The invention consists of ahandle carrying afixed toothed jaw and anangularj aw, and an arm pivoted on the said handle and carrying a cutterto operate in conjunction with the said angular jaw and also formed witha movable jaw to operate in conjunction with the fixed toothed jaw.

The invention also consists of certain parts and details, andcombinations of the same, as will be hereinafterdescribed, and thenpointed out in the claims.

Reference is to be had to the accompanying drawings forming a part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures. t

Figure 1 is a side elevation of the improvement. Fig. 2 is an edge viewof the same with parts in sections, and Fig. 3 is a cross section of thesame on the line 33 of Fig. 1.

The improved pipe wrench and cutter is provided with a handle A formedwith the curved end B on the front edge of which is secured a toothedjaw O, and on the inner edge of which is fastened an annular jaw Dprovided on its faces with V-shaped ridges D, as plainly illustrated inFigs. 1 and 3. The angular jaw D operates in conjunction with a cutter Elocated directly opposite the jaw D and journaled in an extension F ofan arm F pivoted at G to the end B of the handle A, the said arm F beingprovided with a fixed jaw H operating in conjunction with the toothedjaw O.

A screw I screws in an offset J formed on the handle A, the inner end ofthe said screw abutting on the extension F of the arm F so as to imparta swinging motion to the latter on screwing up the screw I. The latteris provided at its lower end with a handle K for Serial No. 467.499. (Nomodel.)

conveniently turning the said screw I to adjust the cutter E relative tothe fixed angular jaw D or the curved jaw H relative to the toothedcurved jaw C.

When the device is to be used as a pipewrench, the arm F is swungoutward on its pivot G in the direction of the arrow at so as to permitof passing the tool with. the jaw 0 lease the pipe sufficiently toprevent turning of the same, and on the further forward movement of thehandle A the pipe is again turned.

When it is desired to cut the pipe in two parts, the screw I is screweddown sufficiently to permit of swinging the arm F in the inversedirection of the arrow at to permit of entering the pipe between thecutter E and the angular jaw D. When the pipe is placed between the two,then the screw I is screwed up until the V-shapedcutter E engages withits cutting edge, the pipe periphery at one side, the opposite sidebeing engaged by the ridges D of the angular jaw D. The operator thenmanipulates the handle A in the usual manner by swinging the same aroundthe pipe so that the cutter E cuts an annular groove in the pipe. Theoperator continues screwing up the screw I so as to move the cutter Etoward the jawD to deepen the cut, until finally the pipe is completelycut in two on the further manipulation of the handle A, as abovedescribed.

It will be seen that this device is very simple and durable inconstruction, and can be readily utilized for turning a pipe or forcutting the same in two parts, it being understood that in either casethe screw I is essential, as the same serves as a stop for the arm F inturning the pipe and also as a means for moving the cutter E toward thejaw D to deepen the cut in the pipe.

As illustrated in Fig. 1, the handle A is formed with a taperingaperture A for enabling the operator to use this end of the handle as awrench on plug nuts of a size corresponding to the size of the pipe forwhich the wrench is designed.

Having thus fully described my invention, I claim as new and desire tosecure by Letters Patent 1. A pipe wrench and cutter comprising a handlecarrying a fixed toothed jaw on one edge and an auxiliary jaw on theopposite edge, and an arm pivoted on the said handle and carrying acutter to operate in conjunction with the said auxiliary jaw, and acurved jaw to operate in conjunction with the fixed toothed jaw,substantially as shown and described.

2. A pipe wrench and cutter comprising a handle carryingafixed toothedjaw on its outer edge and an angular jaw on its inner edge, an armpivoted on the said handle and carrying a cutter to operateinconjunction with the said angular jaw, a curved jaw to operate inconjunction with the fixed toothed jaw, and a screw screwing in the saidhandle and engaging an extension of the said arm, substantially as shownand described.

3. A pipe wrench and cutter comprising a handle formed with a curvedend, a toothed jaw secured to the outer edge thereof, an angular jawsecured to the inner edge of the said end and provided with V-shapedridges, an arm pivoted on the said handle end and provided with anextension and a curved jaw, which latter operates in conjunction withthe said toothed jaw, and a cutter journaled in the said extension ofthe said arm and operating in conjunction with the said angular jaw,substantially as shown and described. I

4. A pipe wrench and cutter comprising a handle formed with a curvedend, a toothed jaw secured to the outer edge thereof, an angular jawsecured to the inner edge of the said end and provided with V-shapedridges, an arm pivoted on the said handle end and provided with anextension, and a curved jaw which latter operates in conjunction withthe said toothed jaw, a cutter journaled in the said extension of thesaid arm and operating in conjunction with the said angular jaw, and ascrew screwing in the said handle to engage the said extension,substantially as shown and described.
